ppp_mppe discards 50% of packets from some servers [2.] Full description of the problem/report: When I connect to a server using MPPE, I receive about every other packet with the FLUSHED bit turned off. These packets are dropped by ppp_mppe.c just like the SPEC says they should be. I am not able to maintain tcp connections through the VPN with these packets being discarded. I found a patch discussed here: http://ubuntuforums.org/showthread.php?t=1095189 When I stop dropping those packets (by making this change to the driver; see patch at end), the problem went away. When I connect to a different server, I do not have this problem. WhenI connect using Windows XP or Windows 7 clients, I do not have any packet loss on either server, though I have not confirmed whether every other packet still has the FLUSHED bit turned off. I could see the symptom clearly by pinging a machine on the VPN. Every other ping packet is lost with the old driver. Once I installed the new driver, every ping is responded correctly. I do not know any details about the two servers (one that works and one that doesn't) except both are managed by the same mega-company but in different countries (China and Czech). --- /etc/ppp/peers/server1 pty "pptp remote-server1 --nolaunchpppd" name "username" remotename PPTP require-mppe-128 file /etc/ppp/options.pptp --- /etc/ppp/options.pptp: lock noauth refuse-pap refuse-eap refuse-chap refuse-mschap nobsdcomp nodeflate [3.] Keywords (i.e., modules, networking, kernel): ppp_mppe.ko, networking, kernel, mppe [4.] Kernel information [4.1.] Kernel version (from /proc/version): Linux version 3.0.0-14-generic (buildd@allspice) (gcc version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) ) #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC 2011 [4.2.] Kernel .config file: *shrug* [5.] Most recent kernel version which did not have the bug: I have never seen a version able to connect to the failing server reliably.

notes, patches, fixes, workarounds: Subject: [PATCH] ppp_mppe: Don't discard non-FLUSHED-bit packets In mppe_decompress, packets without the FLUSHED bit set are discarded. Some servers clear this bit on every other packet and so streams are impossible to maintain. Fix this by keeping these packets with the FLUSHED bit set. This may turn out to be the wrong way to fix this, but it has worked for me so far. I only connect to three servers, though. --- drivers/net/ppp/ppp_mppe.c | 6 ------ 1 file changed, 6 deletions(-) diff --git a/drivers/net/ppp/ppp_mppe.c b/drivers/net/ppp/ppp_mppe.c index 9a1849a..765c28a 100644 --- a/drivers/net/ppp/ppp_mppe.c +++ b/drivers/net/ppp/ppp_mppe.c @@ -517,12 +517,6 @@ mppe_decompress(void *arg, unsigned char *ibuf, int isize, unsigned char *obuf, state->sanity_errors += 100; sanity = 1; } - if (!state->stateful && !flushed) { - printk(KERN_DEBUG "mppe_decompress[%d]: FLUSHED bit not set in " - "stateless mode!\n", state->unit); - state->sanity_errors += 100; - sanity = 1; - } if (state->stateful && ((ccount & 0xff) == 0xff) && !flushed) { printk(KERN_DEBUG "mppe_decompress[%d]: FLUSHED bit not set on " "flag packet!\n", state->unit); -- 1.7.10.509.g991919 -- To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
